These are out of the ones I've heard.
Philippa Soo: Definitely the best Eliza! Amazing singing and acting, so pretty. She's extremely talented, and definitely my favorite.
Zoe Jensen: I really dislike her singing. She sings like she's five. I don't know about her acting skills, but she doesn't suit any of the sisters, or any female musical character I can think of. She's my least favorite Eliza.
Sharon Rose: Incredibly talented, but definitely miscast. She'd make a better Angelica. She has an amazing voice, so no hate.
Isa Briones: She should've been kept as Eliza, instead of being cast as Peggy. She's amazing at singing and acting, and is so pretty.
Ari Asfar: She was kinda overacting in Helpless, but she's got a good voice.
Victoria Scovens: Good voice, very talented.
Hannah Cruz: Very pretty, very talented.
Alysha Deslorieux: Amazing at all the sisters, especially Eliza.
Rachelle Ann Go: Incredible voice, and incredible emotion during Burn. She's a great actress and singer.
Denee Benton: Definitely not my favorite. She lacks vocal maturity and emotional depth. She still has a nice voice, but she's not as good as Solea, Pippa, Rachelle, etc.
Stephanie Jae Park: Good voice. She's very talented.
